What is high pulse repetition frequency?

A high pulse repetition frequency pulse doppler radar in which the prf is large enough to have no blind speeds [as given by Eq. (32)] within the expected values of target doppler frequencies.

What is the function of pulse repetition frequency?

Pulse repetition frequency (PRF) indicates the number of ultrasound pulses emitted by the transducer over a designated period of time. It is typically measured as cycles per second or hertz (Hz). In medical ultrasound the typically used range of PRF varies between 1 and 10 kHz 1.

What is the normal range of pulse repetition rates?

What is the normal range of pulse repetition rates? 500 to 2,000 pps. The pulse repetition rate is how many pulses are created in a unit of time.

What is the effect of low pulse repetition frequency PRF to the radar pulse?

10.11.

A low PRF radar has a long unambiguous range but results in blind speeds. On the contrary, a high PRF radar can avoid blind speeds but experiences ambiguity in range. MTI usually refers to a radar in which the PRF is low enough to avoid ambiguity in range but results in blind speeds.
